I thought the answer as to why Eton has produced so many PMs was so obvious I almost didn't read the story at lunch today. But it's good I did, as I had erroneously thought it was a posh school, when really it's quite normal! Eton may not be the most expensive school in Britain, and it certainly does not get the best exam results.

And wasn't Cameron (rightly) criticised for his whole let's fill front bench with my buddies effort?
